Given numbers are 811, 624, 209, 985

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(811, 624) = 506064

GCD(811, 624) = ( 811 x 624 ) / 506064

= 811 / 624

= 811

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

So, Greatest Common Divisor of 811, 624, 209, 985 is 1
